You can restrict downloads by going to the Settings tab and tapping "Configure Album Details", "Download Permission", and "Admins Only". After doing so, normal album members will not be able to download photos or videos from the album.
This setting also prevents screenshots of photos and videos in the Album tab and Recents tab.
Please Note:
• The person who uploaded a photo/video can still download it even if download permission is restricted.
• If a user takes a screenshot in the Album tab or Recents tab, the screenshot will turn out completely black or white.
• The browser version does not support screenshot restrictions.
